A storage adapter is an abstraction that provides read, write, and delete access to a storage solution of any kind. Storage adapters are used to keep session middleware independent of your database provider, and they allow you to pass your own storage solution.

delete: (key: string) => MaybePromise<void>

Deletes a value for the given key from the storage.

has: (key: string) => MaybePromise<boolean>

Checks whether a key exists in the storage.
